Description

  The present invention relates to footwear having a shoe structure in which a toe structure is formed in a toe.

Conventional basement socks are footwear with workability and motor functionality, but their appearance is not suitable for general sports and outings because of the cracking of their fingers. On the other hand, there are shoes with a larger instep and softened armor as footwear for hallux valgus, but there is no effect on those who have already deformed toes, and a partition material is used on the toes. Several intervening patent applications have also been published, but the partition material alone does not match the degree of deformation of the big toe, which is not suitable for long-time implementation. There is also a shoe with a snout, but this also has little effect of actively preventing deformation of the big toe. As described above, once the big toe is bent inward, it is difficult to correct the hallux valgus, and the conventional product does not provide a suitable product. In addition, safety shoes are equipped with a toe as a protective material inside the toes, so that there is a considerable clearance (clearance) in the toes inside the shoes. In the footwear, the toes are laterally shaken and the footwear increases, and this also causes deterioration of work performance.

  In view of the above circumstances, the present invention aims to provide a footwear product having a shoe structure excellent in hallux valgus effect in the style of work wear, sports, and outing.

According to the present invention, an inner member of a sock structure that distinguishes between the thumb using the stretchable fabric and the other four fingers is interposed between the upper material and the toe of the upper part of the shoe sole, and the internal A partition member made of a soft elastic material is attached to the finger crotch of the thumb of the material and the other four fingers. This partition member is the finger crotch root in the finger crotch according to claim 2. Make the wall thickness in the vicinity larger than other parts.
Thus, as described in claim 3, the upper part of the inner member is composed of two stretch fabrics such as nylon and polyester fiber, and the inner part is made of urethane foam intervening, while the lower part is lower. Is a two-piece construction with a stretchable nylon tricot fabric on the inside bottom and a plain woven fabric of synthetic fiber on the surface that contacts the inside of the shoe sole, and with urethane foam intervening inside. As described in claim 4, the inner member is made different in the elasticity of the upper and lower elastic fabrics so that the latter is smaller than the former.

  Further, as described in claim 5, a toe-core material for toe protection such as a steel plate or a reinforced plastic material is interposed between the upper material and the inner member, so that a safety shoe type can be obtained. By the way, as described in claim 6, the partition member that is a characteristic component of the present invention has a thickness of about 3 mm to 10 mm and a length from the toe side to the finger crotch root of about 25 mm to 50 mm, and the height dimension at the finger crotch root is about 20 mm to 30 mm, and an arc is formed from the toe side to the top of the finger crotch root, and at least the finger crotch root of the partition member The upper surface portion of the portion is fixed to the back surface of the upper and the lower surface portion is fixed to the bottom surface of the shoe, respectively. In this case, when the tip core material according to claim 5 is attached, the partition member has the above-mentioned The upper surface portion is fixed to the back surface of the core material.

  The present invention interposes an inner member of a socks structure that distinguishes between the thumb using the stretchable fabric and the other four fingers with respect to the inside of the toe of the footwear having the shoe structure as described above, and A partition member made of a soft elastic material is attached to the finger crotch of the thumb and the other four fingers. Therefore, the finger crotch part inside the toe and the partition member interposed in the finger crotch are inside the toe. And the other four fingers are completely separated, and the partition member, together with the socks structure using the stretchable fabric of the inner member, exhibits a hallux valgus blocking action, that is, a hallux valgus. Even for the thumb, the soft elastic material having a constant thickness and hardness is sandwiched between the finger crotch portions and can be appropriately swung, so that it is possible to always naturally prevent the hallux valgus and correct the action. In this case, when the wall thickness at the finger crotch root portion of the partition member is made larger than the other portions as described in claim 2, the above-mentioned effect is exerted more strongly near the finger crotch root portion. It becomes a thing.

  Further, when the stretchable fabric of the inner member is constructed as described in claim 3 or 4, the above-mentioned hallux valgus action effect can be achieved without any discomfort, particularly in comfort.

In addition, since the conventional underground working socks have no protective members on the toes, no safety measures are taken against falling objects during work, but the present invention is configured as described in claim 5. Therefore, in addition to the hallux valgus effect described above, it contributes to the performance of safety work in field work.
By the way, the structure of a general safety shoe in the past is such that the shape of the tip material provided on the toe is slightly larger than the last of the foot type, so that the toes are inside the toe of the shoe during walking. As a result, a lateral movement occurs without being fixed, so that the treading pressure to the ground cannot be transmitted reliably, and the fatigue of the foot becomes severe during walking as well as during walking. In the present invention having the configuration, the inner member using the stretchable fabric and the soft elastic partition member do not cause a lateral shake of the foot and have excellent adhesion to the ground.
Thus, the overall appearance of the product according to the present invention is a normal toe-shaped shoe shape, so that a person with hallux valgus can comfortably wear it even in public, and wearing it without any discomfort, of course, for sports use It is also effective for special shoes such as working, mountain climbing and golf shoes.

  Although the illustrated example shows a running shoe, the present invention includes all sports shoes, chemical shoes for children, and footwear having a special shoe structure such as safety shoes and climbing shoes.

  FIG. 1 is a perspective view of an inner member 1 according to the present invention, that is, an inner member 1 interposed inside a toe. Here, the elastic fabric used in the upper part (A) of the inner member 1 is composed of two pieces of 1a and 1b using nylon and a tetron-based knitted fabric material, and the urethane foam 1c is interposed inside. The finger crotch portion is sewed to a thickness t of approximately 2 mm to 5 mm, and the first finger and the other four fingers are partitioned at an appropriate interval with respect to the toe portion p as shown in the figure. It is assumed that the front half tabi type in which 2 is formed is formed.

  Thus, the lower part (B) of the inner member 1 is made of a plain weave fabric using synthetic fibers that is inferior in elasticity (including non-elasticity) to the upper part (A). In addition, a two-sheet structure using stretchable nylon tricot fabric is used on the inner bottom side, and urethane foam is interposed in the two-sheet structure in the same manner as described above. At this time, the surface of the lower part (B) that is in contact with the inside of the sole is inferior in stretchability (including non-stretchable) plain weave fabric so that the stitched portion m of the upper part (A) and the lower part (B) In order to prevent the seam of the stitching portion m from moving in the vertical direction of the left and right side portions when the foot-type last is suspended by being always pulled to the inner side of the shoe sole, This is important for making the footwear easy to wear and comfortable to wear without feeling uncomfortable.

  FIG. 2 is a perspective view of the mouthpiece padded 3. The upper end 3a of the foot pad is sewn to the upper side, while the left and right end 3b is sewn to the left and right side portions 1d of the inner member 1.

FIG. 3 shows a partition member 4 to be inserted into the above-described finger crotch portion 2. The partition member 4 is a soft sponge material such as latex sponge, urethane sponge, rubber sponge, EVA sponge, etc., and its hardness is C It is a numerical value indicating approximately 5 to 35 degrees with a hardness meter. By the way, the wall thickness t ′ of the partition member is about 3 mm to 10 mm, the length from the toe side to the finger crotch root is about 25 mm to 50 mm, and the height at the finger crotch root is about 20 mm to 30 mm. In addition, an arc is formed from the lower side of the finger crotch root to the upper side from the toe side. In the illustrated example, a cylindrical body 4a having a width of about 2 mm to 5 mm from the wall thickness from the toe side is formed at a location that comes into contact with the base of the finger crotch.
In the case formed in this way, it is easy to make it possible by making the thickness dimension and the shape of the cylindrical body 4a different as appropriate in order to exert the effect of preventing the progression of the hallux valgus and correcting the object of the present invention. is there.

  FIG. 4 shows the foot type last 5. Here, in order to facilitate the insertion of the partition member 4, the foot last 5 has a toe crotch width 5b dimension of about 3 mm to 7 mm, and the base 5a corresponding to the base of the thumb has a cylindrical shape of about 5 mm to 15 mm. There is.

  FIG. 5 is a partially broken perspective view showing a state in which the shoe 8 is manufactured using the inner member 1 and the partition member 4, wherein 5 is a foot last, 6 is an upper material, and 7 is a bottom material. is there. As can be seen from the figure, in the present invention, the partition member 4 is interposed in the finger crotch portion 2 of the inner member 1 having the above configuration, and the upper part of the columnar bulge 4a of the partition member 4 is at least on the toe side by an adhesive. It is made to adhere to the back surface 6 a of the upper material 6, while the lower part of the columnar bulge 4 a is glued to the bottom material 8. On the other hand, the toe side is hung in accordance with the shape of the last of the foot type, and usually finished in a round shape of the toe of a shoe, and then attached to the bottom material 7 coated with an adhesive.

  FIG. 6 is a product drawing. In the present invention, as described above, the inner member 1 using a stretchable fabric and the partition member 4 having an appropriate hardness are mounted on the toe side between the upper material and the shoe sole, and other configurations are the same as conventional shoes. Manufactured by.

  At the time of gluing in the above, the upper surface portion (cylindrical bulging body 4a in the illustrated example) serving as the base of the finger crotch portion of the partition member 4 is fixed to at least the back surface 6a of the upper material 6 with an adhesive. However, the other arcuate portion 4b is not necessarily fixed. However, the bottom surface portion 4c of the partition member 4 is necessarily fixed to the bottom material 7 with an adhesive. On the other hand, the upper (A) upper surface fabric 1a composed of the two inner members 1 is bonded to the back surface 6a of the upper material 6, while the lower (B) plain weave fabric is also composed of two inner members. Is fixed to the bottom material 7 with an adhesive. By the way, the side surface portion 4d forming the plate-like portion of the partition member 4 may be fixed to the inside of the finger crotch formed on the inner member 1 with an adhesive. It has been found that it is preferable to place it in a freely swingable state without making it.

  In the present invention, the inner member 1 is made of a stretchable fabric and has a front socks type configuration, and the partition member 4 interposed between the finger crotch portion that distinguishes the thumb from the other four fingers at the toe portion. With the synergistic action, the appropriate pinching pressure and the elastic / repulsive pressure associated therewith always act, and in combination with the fact that the partition member 4 is soft elastic and swingable, It becomes a very pleasant stimulus.

  The present invention is configured as described above, and is an easy-to-wear product whose appearance is the same as that of a conventional athletic shoe, and has a stimulating action at the finger crotch part that cannot be obtained from the conventional product at all when used for walking. Specifically, the partition member divides the toes to give each toe a strong feeling of grounding, which not only improves stability to prevent lateral shaking during grounding, It is possible to promote health promotion by stimulation at the same time. Thus, it contributes to the prevention of the hallux valgus, the corrective action, and the reduction of fatigue, which are the objects of the present invention.
